The post-entry operation sustainability of airline routes directly affects their profitability. This paper investigates factors influencing the operating duration of airline routes based on a survival analysis modeling method. Key factors are selected from five aspects representing characteristics in terms of cost and supply, route and airport, market structure, airline cooperation type, and time heterogeneity. The transatlantic market between Europe and the US is chosen as the empirical study due to its high degree of liberalization. The research period ranges 19 years from 2003 to 2021. First, the single factor analysis is conducted by utilizing the Kaplan-Meier method. Second, a Weibull parameter survival model is constructed to quantitatively analyze the relationship between the chosen factors and the operating duration of airline routes. The results show that：(1) The average operating duration of the EU-US routes is five years, among which routes that were continuously operated for more than 10 years account for 16%；(2) the operating duration of airline routes is significantly influenced by distance, airline’s total capacity, route structure, endpoint airports type, route competition, airline type, and region as well as alliance；(3) both independent and interaction variables representing alliance and code-share characteristics have significant impacts on route operating duration. Routes operated by Star and SkyTeam members have a longer operating duration. For airlines in the same alliance, the route-exit risks between operating carriers and marketing carriers in code-sharing cooperation are significantly different. [ABSTRACT FROM AUTHOR]

The operational decision-making of low-carbon supply chains with different market structures is studied under the conditions of monopoly and duopoly competition. Considering that the uncertainty about investment in emission reduction technology innovation will lead to disappointment aversion among manufacturers. The constructing corresponding game models are constructed in both cases, and the relevant decision-making issues such as the investment level in emission reduction technologies and pricing of the low-carbon supply chains are discussed. The results show that in a monopoly situation, the investment level in emission reduction technologies, and the manufacturer utility are all negatively related to the disappointment aversion coefficient, and positively related to the investment cost efficiency of emission reduction technologies. In a competitive situation, whether low-carbon manufacturers dominate or both parties have equal power, equilibrium results are negatively related to the disappointment aversion coefficient, and positively related to the unit travel cost of consumers, retail price of low-carbon products are higher when low-carbon manufacturers dominate than that when power is equal; the investment level in emission reduction technologies when low-carbon manufacturers are dominant is lower than that when the powers of the two parties are equal, and in all power structures, the expected profit and utility of low-carbon manufacturers are negatively related to the investment cost coefficient in emission reduction technologies, while ordinary manufacturers are on the contrary.

The complex network theory is used to analyze the structural complexity of the global international aviation network, and the internal structural characteristics of the global international aviation network are analyzed with the community structure theory by using the Newman fast algorithm to identify and divide cities in the network. The results show that the degree and the distribution of the global international aviation network have spatial differences, the average path length is short and the clustering coefficient is large, the absolute and relative gaps of tight centrality are small, the intermediate centrality distribution function is a power function. Cities in the network are divided into 18 communities with great scale differences. Cities with close geographical locations are more likely to form the same community, but some cities also show long-distance interaction. The boundaries of communities on all continents are distinct, while many boundaries are fuzzy and various inside Europe. It indicates that the global international aviation network has the characteristics of "scale-free network" and "smallworld network", and the network is dominated by a small number of high degree value cities, with strong aggregation and high global efficiency. A few cities assume the main intermediary function, and most cities have almost no transit capacity. There is significant heterogeneity in the scale of community networks, and the distribution of community networks has obvious characteristics of geographical clusters, but the geographical proximity of cities may not be closely connected. Large groups have better internal connectivity, while small groups have higher internal network density. The international aviation market structure on all continents is stable, while Europe has not yet formed a stable aviation connection. [ABSTRACT FROM AUTHOR]

Based on the game models under different market structures, the impacts of different competition modes on upstream manufacturers ' innovation investment decision-making in horizontal and vertical dimensions were discussed. The results showed that the horizontal market competition intensity has a negative effect on upstream manufacturers ' innovation investment willingness, while the vertical market power has a positive effect on upstream manufacturers' innovation investment willingness. However, compared with the benchmark situation without competition pressure, both horizontal and vertical competition will reduce manufacturers ' motivation to invest in research and development innovation, and the double competition pressure from the horizontal and vertical dimensions will aggravate this inhibition. Finally, through numerical analysis, the correctness of the obtained results is verified. [ABSTRACT FROM AUTHOR]

The economics literature contains many theoretical analyses of imitation and differentiation strategies but relatively few empirical studies of these topics due to the limitation of data and methods. This paper conducts empirical research on competitive behavior among three dominant Chinese satellite TVs. It indicates that: 1) Program selection decisions of dominant satellite TVs primarily depend on their previous decision, showing decision inertia, which is verified by the fact that shock of each satellite TV's previous decisions best explains its current decision. Meanwhile, there is strategic dynamic interaction between each other, in the form of a mixed strategy with both imitation and differentiation. 2) Degree of imitation depends on satellite TVs' competitive positions. Leaders tend to differentiate, while pursuers incline to imitate. 3) Satellite TVs' decision patterns show heterogeneity related to program types. A satellite TV's decisions on its representative and advantageous programs are less affected by its competitors, while decisions on other programs suffer greater impacts. And heterogeneity is more obvious in pursuers. Impacts of market structure and degree of imitation on program ratings are further studied. Results indicate that: 1) Competitive pressure has negative crowd-out effect on leaders' program ratings, while it has positive spillover effect on pursuers. This finding is consistent with the fact that rating gap between first-class dominant satellite TVs and second-class dominant ones has narrowed. 2) Imitation leads to higher program ratings, indicating possible presence of herd behavior among Chinese audience.
